BACKGROUND OF THE INVENTION

1. Field of the Invention

The present invention generally relates to motor vehicles. Moreparticularly, the present invention relates to a window assemblyincluding a window frame adapted to releasably mount to a lower doorassembly of a motor vehicle which cannot be removed when the lower doorassembly is in a closed position.

2. Discussion

It is well known in the motor vehicle art to provide a convertible topwhich may be folded back or removed from the vehicle. In one commonform, the convertible top is constructed of a flexible fabric (referredto as a soft top) and can be folded back to a storage position orotherwise removed from an installed position. In another common form,the convertible top is constructed from a rigid material such as plasticand/or metal (referred to as a hard top) and is intended to becompletely removed from the vehicle.

Soft tops are desired by a large segment of purchasers since theyprovide the user with the benefit of open air driving while affordingavailable protection in the event of adverse weather conditions. Mostknown soft tops are designed to be easily retracted to a storedposition, either under a source of power or manually. Other factorswhich make soft tops desirable include less associated expense, readilyremovable panels, and compact storage size. Among other advantages,vehicle hard tops provide for greater comfort and noise due to reducedwind and road noise and improved insulation from extreme ambientconditions.

It is also known in the art of motor vehicles to provide a single motorvehicle designed to cooperate with both a soft top and a hard top. Onesuch vehicle is sold by the assignee of the present application undertheir registered trademark JEEP. While JEEP® brand vehicles having topsystems with both a soft top and a hard top have been extremely popularwith consumers, it remains desirable to further improve certain aspectsof such top systems. The present invention addresses improvements toknown top systems for motor vehicles, including the top system for JEEP®brand vehicles.

SUMMARY OF THE INVENTION

It is a principal object of the present invention to provide a removablewindow assembly for a motor vehicle which cannot be removed when theassociated door is closed but may be easily removed when the associateddoor is open.

It is a more particular object of the present invention to provide aremovable window assembly for a motor vehicle which utilizes thefriction of pins inserted into body panel grommet receptacles and thegeometry of the windshield frame shut-face to prevent the window frombeing removed when the vehicle door is closed.

In one form, the present invention provides a window assembly for amotor vehicle including a lower door assembly pivotally attached to themotor vehicle for movement between an open position and a closedposition, a windshield frame and a sport bar assembly. The windowassembly includes a window frame and a mounting arrangement forremovably attaching the window frame to the lower door assembly suchthat substantial vertical translation of the window frame is required toremove the window frame. The window assembly further includes a stopsurface carried by the motor vehicle which is adapted to oppose verticaltranslation of the window frame when the lower door assembly is in theclosed position.

A quarter window 42 is attached to each of thelaterally spaced apart side sections 38 with a zipper 44. In a similarmanner, a zipper 46 attaches a rear window 48 to the rear section 40.

With the foregoing description of the exemplary motor vehicle 10 asbackground, the various specific features of the present invention willnow be described.

I. APPARATUS FOR ARTICULATING THE SOFT TOP BETWEEN AN OPERATIVE POSITIONAND A STORED POSITION

With specific reference to FIGS. 2, 4, 5 and 7-10, the fabric of thesoft top 12 of the present invention is to include an apparatus forarticulating the soft top 12 between the operative position and thestored position. As will become apparent below, the apparatus furtherfunctions to support the soft top 12 in its operative position betweenits operative and stored positions.

The apparatus for articulating the soft top 12 has a plurality ofsupport members including a forward support member 100 (or #1 bow), anintermediate support member 102 (or #2 bow), and a rearward supportmember 104 (or #3 bow). The #1 bow comprises a header portion 100 whichis conventionally sewn within a forward edge 50 of the top section 36 ofthe soft top 12 (shown in FIG. 12). The #2 bow 102 transversely extendsacross the underside of the soft top 12 for supporting the fabric of thesoft top 12 in a cross-car direction and the #3 bow supports an upperrear corner 52 of the soft top 12 when the soft top 12 is in theoperative position.

The #1 bow 100 is interconnected to the motor vehicle 10 for rotationabout a first transverse pivot axis through a pair of side bows 106. Theside bows 106 are each generally L-shaped, having a first end 107operatively interconnected with the #1 bow 100 and a second end 108pivotally attached to the main hoop 20 of the sport bar assembly 16. Thesecond ends 108 of the side bows 106 are each received in a knuckle 110which is pivotally attached to a respective mounting plate 112. Themounting plate 112 is fixedly attached to an associated vertical member22 of the main hoop 20 of the sport bar assembly 16 with threadedfasteners 114. The second ends 108 of the side bows 106 cooperate todefine the first transverse pivot axis.

The #3 bow 104 extends in a transverse direction and is captured withinthe upper rear edge 52 of the soft top 12. The #3 bow 104 is preferablyintegrally formed with a pair of L-shaped members 116 which function topivotally interconnect the #3 bow 104 to the motor vehicle 10 forrotation about a second transverse pivot axis. Both of the L-shapedmembers 116 of the #3 bow 104 include an end 118 which is received intoa knuckle 120 pivotally attached to the mounting plate 112. The ends 118of the L-shaped members 116 cooperate to define the second transversepivot axis. In the preferred embodiment, the first and second transversepivot axes are spaced apart from each other both vertically andhorizontally.

As shown most clearly in the top sectional view of FIG. 5, the L-shapedmembers 116 attaching the #3 bow 104 to the sport bar assembly 20 bothdiverge in an outboard direction as they extend from the sport barassembly 20. This geometry provides a full shape for the soft top 12 inits operative position while allowing the plurality of support members100, 102, and 104 to be positioned entirely within the body 18 of thevehicle 10 when the soft top 12 is stored. The significance of thisfeature will become more apparent below when concurrent mounting of thehard top 14 and the soft top 12 to the motor vehicle 10 is described.

The specific manner in which the soft top is installed is describedbelow. Briefly, when the side sections 38 and the rear section 40 of thetop 12 are attached to the motor vehicle 10, the L-shaped members 116are permitted to flex. Such flexing provides a spring load which servesas a counter-force to the fabric of the soft top 12, thereby retainingthe soft top 12 in a taut condition.

The #2 bow 102 includes two downwardly extending ends 121 (shown mostclearly in FIG. 9) which are supported on an associated one of the sidebows 106 when the soft top 12 is in its installed position. To this end,each downwardly extending end 121 of the #2 bow 102 is attached to asupport member 122 which defines a groove 124 for receiving one of theside bows 106. The #2 bow 104 is preferably pivotally interconnected toeach of the side bows 106 through a link rod 126.

The apparatus for articulating the soft top 12 of the present inventionfurther includes a pair of tension straps 128. Each of the tensionstraps 128 includes a first end 130 attached to one of the downwardlyextending ends 121 of the #2 bow 102 and a second end 132 attached toone of the side bows 106 immediately adjacent the #3 bow 104. Thetension straps 128 cooperate to draw the soft top 12 taut in alongitudinal direction when the soft top 12 is in its operativeposition.

When the soft top 12 is articulated from its stored position (shown inFIG. 2), through an intermediate position (shown in FIG. 8), andultimately to an operative position (shown in FIG. 1), the side bows 106function to carry the #1 bow 100 and the #2 bow 102 throughcorresponding pivoting arcs from a cavity located between the rear seat53 and the tailgate 54 to the top of the windshield frame 32.Concurrently, the #3 bow 104, which when the soft top 12 in itsoperative position frames and supports the upper rear corner 52 of thesoft top 12, pivots about the second transverse pivot axis which isdisposed immediately rearward and below the first transverse pivot axis.The #3 bow 104 pivots down to rest on the top of the rear wheel housepanels 56 which are inboard of the body side panels 58 and forward ofthe tailgate 54. As the side bows 106 articulate forward, the #2 bow 102pivots on the side bows 102 to clear the rear hoops 26 of the sport barassembly 16. The #2 bow 102 comes to rest on the top of the L-shapedmembers 116, and the side bow 106 and the #1 bow 100 come to rest on topof the #2 bow 102.

In the stored position, the fabric of the soft top 12 is attached to the#1, #2, and #3 bows 100, 102 and 104 and is folded around and into astowed bow assembly to form a minimal visible stack. A wrap or boot (notshown) may be used to gather the loose fabric and also may be used tocontain the rear and quarter windows 48 and 42.

II. REMOVABLE DOOR FRAME ASSEMBLY

With specific reference to FIGS. 14, 15 and 20-28, the top system of thepresent invention is shown to include a removable door frame assembly200. The removable door frame assembly 200 shown throughout the drawingsis specifically configured for the driver's side of the motor vehicle10. However, it will be understood by those skilled in the art that theexemplary motor vehicle 10 includes a removable door frame assembly forthe passenger's side which is a substantial mirror image thereof. Aswill become apparent below, the removable door frame assembly 200continues the shut-face or opening aperture into which either a fulldoor 59 or a removable window assembly 300 for a lower door assembly 60sits. The removable door frame assembly 200 further functions to retainthe top section 36 of the soft top 12 in a cross-car direction and theside section 38 of the soft top 12 in a longitudinally direction.

The removable door frame assembly 200 is shown to include a firstportion 202 which is adapted to releasably engage the motor vehicle 10in a horizontal orientation and a second portion 204 adapted toreleasably engage the motor vehicle 10 in a vertical orientation.Preferably, the first and second portions 202 and 204 are pivotallyinterconnected with a pin 206. Such pivotal interconnection permits theremovable door frame assembly 200 to be folded (as specifically shown inFIG. 28), thereby facilitating storage within the motor vehicle 10 uponremoval.

With particular reference to the cross-sectional view of FIG. 22, thefirst portion 202 of the removable door frame assembly 200 is integrallyformed to include a pair of mounting portions 208. The mounting portions208 are similarly constructed to include an upper flange 210 and a lowerflange 212 which cooperate to partially define an arcuate recess 214.The arcuate recess 214 is sized to receive one of the side bars 28 ofthe sport bar assembly 16. The upper and lower flanges 210 and 212 areformed to include aligning apertures 216 and 218, respectively, adaptedto receive a threaded fastener 220. The fastener 220, which has anoversized head 222 to facilitate manual installation, is passed throughthe aperture 216 in the upper flange 210, through an aperture 224 in theside bar 28, and engages a captured nut (not specifically shown)provided in the lower flange 212.

An upper side 226 of the first portion 202 is integrally formed toinclude a longitudinally extending recess 228 which accommodates anadjacent one of the side bows 106 when the soft top 12 is in theoperative position. The first portion 202 is further integrally formedto include a downwardly extending lip 230 which partially defines thedoor shut-face. The downwardly extending lip 230 is adapted to abut aseal 62 carried by the full vehicle door 59 or the removable windowassembly 300.

The second portion 204 of the removable door frame assembly 200 isintegrally formed to include a lip or flange 232 (shown most clearly inFIG. 21) which forwardly extends and cooperates with the downwardlyextending lip 230 of the first portion 202 to partially define the doorshut-face. A lower end 234 of the second portion 204 is formed toinclude a cylindrical aperture 236 for receiving a locating pin 240. Thelocating pin 240 is adapted to engage a B-pillar grommet assembly 242carried by the vehicle body 18.

The lower end 234 of the second portion 204 is further integrally formedto include a downwardly extending flange 243 which cooperates with thebody 18 of the vehicle 10 to prevent rotation of the second portion 204relative to the motor vehicle 10. Thus, the pin 240 and flange 243cooperate to provide positive containment of the removable door frameassembly 200 in the longitudinally and cross-car directions, while beingpassive in a vertical direction. Vertical containment of the removabledoor frame assembly 200 is managed through the molded upper and lowerflanges 210 and 212 of the first portion 202 which are attached to theside bar 28.

The first and second portions 202 and 204 of the removable door frameassembly 200 are formed to include molded-in-channels 244 and 246,respectively, for retaining the soft top 12 in an operative position. Inthis regard, the molded-in-channel 244 of the first portion 202 extendsin a generally longitudinally direction and is adapted to removablyreceive a retainer element 400 fixedly attached to the top section 36 ofthe soft top 12. As shown most clearly in the cross-sectional view ofFIG. 22, the molded-in-channel 244 of the first portion 202 is definedby a generally U-shaped segment 248 of the first portion 202 which opensdownwardly. The distal end of the segment 248 is angled slightly outwardas it extends down to facilitate entry of the retainer element 400. Theretainer element 400, which is described in more detail in Section IVbelow, is retained under the tension of the top section 36 of the softtop 12, thereby retaining and tensioning the soft top 12 in a cross-cardirection.

In a similar manner, the molded-in-channel 246 (shown most clearly inFIG. 21) of the second portion 204 of the removable door frame assembly200 is defined by a generally U-shaped segment 250 which is adapted toreceive a portion of a U-shaped forward retainer element 62 fixedlyattached to the side portion 38 of the soft top 12. In the preferredembodiment, the retainer elements 62 and 400 are attached to theirassociated portions of the soft top 12 through stitching (not shown).The molded-in-channel 246 of the second portion 204 functions tolongitudinally retain the side section 38 of the soft top 12.

III. REMOVABLE DOOR WINDOW ASSEMBLY

With specific reference to FIGS. 29-31, the removable window assembly300 of the present invention is shown to include a wire window frame 302which defines a window opening 304 and a mounting arrangement forremovably attaching the wire window frame 302 to the lower door assembly60. In the exemplary embodiment illustrated, the mounting arrangementincludes a plurality of wire pins 306 interconnected to the window frame302 in a corresponding plurality of grommet assemblies 308 provided inan upper surface 310 of the lower door assembly 60. The wire pins 306are preferably L-shaped so as to position the outer surface of the doorand its seals relative to the grommet assemblies 308.

The wire of the wire window frame 32 has a diameter sufficient to holdit against the seal flange (not specifically shown) carried by thewindshield frame 32. The grommet assemblies 308 define apertures 312 forreceiving the pins 306 as a result of limited clearance between the pins306 and their corresponding apertures 312, the window frame 302 must belifted in a substantially vertical direction in order to remove it fromthe lower door assembly 60.

The window frame 302 is configured to cooperate with the shut-facesurface which is cooperatively provided by the lateral edge 64 of thewindshield frame 32 and the removable door frame 200. In this regard,the downward extending flange 230 of the removable door frame assembly200 and a similar flange provided by the lateral edge 64 of thewindshield frame 32 to prevent removal of the window frame 303 when thelower door assembly 60 is in the closed position. The lateral side 64 ofthe windshield frame 32 and the removable door frame assembly 200laterally extend beyond the window frame 302. Thus, the windshield frame32 and the removable door frame assembly 200 cooperate as a passiveinterference device to prevent the window frame 302 from being removedwhen the lower door assembly 60 is closed while allowing the windowframe 302 to be easily removed when the lower door assembly 60 is open.

IV. RETAINER MEMBER FOR ATTACHING THE SOFT TOP TO THE MOTOR VEHICLE

With specific reference to FIG. 14, and the cross-sectional views ofFIGS. 22 and 29, the retainer member 400 introduced above in Section IIregarding the removable door frame assembly 200 will be furtherdescribed. The retainer member 400 functions to retain the fabric of thesoft top 12 in a cross-car direction (i.e., a transverse direction) andfurther functions to shingle the vehicle door 59 or 60 by forcing water(e.g., rain and condensation) to fall away from the top of the door 59or 60, thereby preventing water intrusion.

As shown in the perspective view of FIG. 14, the present inventionpreferably includes a pair of substantially identical retainer members400 which interconnect a lateral edge 66 of the top section 36 of thesoft top 12 with the molded-in channel 244 of the first portion 202 ofthe removable door frame assembly 200. Each retainer member 400 isintegrally formed of a rigid plastic material to include a first portionpreferably in the form of a first flange 402. The first flange 402 isadapted to be fixedly attached to the lateral edge 66 of the soft top12. In the exemplary embodiment, the lateral edge 66 of the soft top 12wraps around an edge 404 of the first flange 402 and is sewn to thefirst flange 402.

Each of the retainer members 400 is shown to further include a secondportion 406. The second portion 406 is illustrated to preferablycomprise a second flange 406 adapted to be inserted into the molded-inchannel or recess 244 of the removable door frame assembly 200 andcooperate with the channel 244 to oppose a bending moment introduced bytensioning of the soft top 12 in a lateral direction. The second flange406 is shown to be preferably disposed at an obtuse angle relative tothe first flange 402.

As shown in the cross-sectional views of FIGS. 22 and 29, the channel244 defined by the removable door frame assembly 200 is integrallymolded into the first portion 202 of door frame assembly 200 and opensin a generally downward direction. The opposing sides 252 and 254 whichdefine the molded-in channel 244 retain the retainer member 400 in aninterference fit. In this regard, the second flange 406 of the retainermember 404 is fully inserted into the channel 244. The tension of thefabric top 12 in a lateral direction introduces a bending moment to theretaining element 400 which is opposed through contact of the opposingsides 252 and 254 with the second flange 406, thus holding the soft top12 cross-car between the doors 59. The first flange 402 laterallyextends beyond the removable door frame assembly 200 so thatcondensation and rain is laterally carried away from the door 59.

Turning to FIG. 32, an alternative construction of a retaining member400' is illustrated. In this construction, the first flange 402' isupwardly turned and interconnected to the second flange 406' through anintermediate portion 412. The first and second flanges 402' and 406' andthe intermediate portion 412 cooperate to define a rain trough 414 forcarrying water and condensation rearward. Preferably the fabric of thesoft top 12 is attached (e.g., sewn) to both the intermediate portion412 and the first flange 402'.

V. AN APPARATUS FOR SELECTIVELY MOUNTING THE HARD TOP AND THE SOFT TOPTO THE MOTOR VEHICLE

With specific reference to FIGS. 2, 6, 19, 22 and 23, the presentinvention is shown to include an apparatus 500 for selectively mountingthe hard top 14 and the soft top 12 to the motor vehicle 10. As willbecome apparent below, the apparatus for selectively mounting the hardtop 14 and the soft top 12 further functions to cover a raw sheet metaledge of the body side panel 58 in an effective and cost efficientmanner. Pertinent to the present invention, the body side panel 58(shown most clearly in FIG. 22) of the motor vehicle 10 upwardly extendsand includes a generally horizontal upper portion 70. The body sidepanel 58 also includes a downwardly extending distal flange 72 on theinboard side which terminates at a raw edge 74.

The apparatus comprises a retaining member 500 which is longitudinallyelongated to extend the entire length of the body side panel 58 of themotor vehicle 10. The retainer member 500 is shown to generally includean intermediate portion 502, an outboard flange 504 and an inboardflange 506. The intermediate portion 502 is adapted to be horizontallyoriented and fixedly attached to the generally horizontal upper portion70 of the body side panel 58. In the preferred embodiment 502, theintermediate portion 502 is welded to the body side panel 58. As shownin FIG. 19, the retainer member 500 preferably extends around a rearcorner 82 of the motor vehicle 10 and includes a substantially identicalportion which is attached to a sheet metal panel adjacent the vehicletailgate 54.

The upper surface of the intermediate portion 502 provides a flatsurface for supporting the hard top 14. As shown in FIGS. 5 and 6, thehard top 14 includes an inwardly extending flange 76 which rests on theintermediate portion 502. Threaded fasteners 78 pass through apertures(not specifically shown) provided in the inwardly extending flange 76and engage captured nuts 509 retained by the intermediate portion 502.

The outboard flange 504 downwardly extends from the intermediate portion502 and terminates in an inner curled portion 510. The inner curledportion 510 is spaced apart from the outer surface of the body sidepanel 58 of the motor vehicle 10 and defines a gap 512 for receiving oneor more rigid retainers 80 (identified in FIG. 15) attached to thebottom edge of the side section 38 of the soft top 12. When the hard top14 is mounted to the vehicle 10, the inner curled portion 510 presents anon-functional but aesthetically pleasing appearance.

The inboard flange 506 extends downwardly beyond the downwardlyextending distal flange 72 of the body side panel 58. The inboard flange506 terminates at a curled inner edge 514. The curled inner edge 514functions to conceal the raw sheet metal edge 74.

In the preferred embodiment, the retainer member 500 is a one-piece,seamless and continuous part constructed from steel. The retainer member500 is preferably welded to the body side panel 58 before the motorvehicle 10 is painted. By attaching the retainer member 500 a motorvehicle 10, a customer may initially purchase a hard top 14, and at anylater date add a soft top 12 without the necessity of adding any bodyside retainers for properly retaining the soft top 12.

VI. APPARATUS FOR LATCHING THE HARD TOP OR THE SOFT TOP TO THE MOTORVEHICLE

With specific reference to FIGS. 11-13, an apparatus 600 for latchingthe hard top 14 or the soft top 12 to the motor vehicle 10 (e.g., alatching arrangement 600) of the present invention will be described.The latching arrangement 600 as it relates to the soft top 12 is shownin FIG. 12 and as it relates to the hard top 14 in FIG. 13. The latchingarrangement 600 includes a latching mechanism 602 for the soft top 12, alatching mechanism 604 for the hard top 14, and a horizontally elongatedslot 606 located in an upper portion of the windshield frame 32. Theslot 606 in the sheet metal of the windshield frame 32 is extruded andformed to present a rugged, durable attachment area.

As shown in FIGS. 12A and 12B, the latching mechanism 602 for the softtop 12 includes a pair of base plates 608 attached to the header 100, amanually displaceable handle 610 and a hook member 612. The handle 610is pivotally attached to the base plates 608, which are attached tospaced apart portions of the header 100. In this regard, the handle 610is pivotable about an axis defined by a pin 614 between a latchedposition (shown in solid lines in FIG. 12A) and an unlatched position(shown in broken lines in FIG. 12B).

The hook member 612 of the latching mechanism 602 for the soft top 12 isshown in FIG. 12B pivotally attached to the handle through a pin 616.The pivot axis for the hook member 612 defined by the pin 616 is offsetfrom the pivot axis for the handle 610. When the handle 610 is in itslatched position, the pivot axis for the hook member 612 is slightlyabove the pivot axis for the handle 610. As a result, an undercentermechanical geometry (essentially an overcenter mechanical geometry witha reverse orientation) is established between the two pivot axes.

In latching the soft top 12 to the windshield frame 32, the handle 610is rotated downward to its latched position, and the hook member 612 isengaged with the horizontally elongated slot 606. Such downward rotationof the handle member 610 draws the hook member 612 upward to engage theslot 606. The handle 610 provides a lever arm for creating the necessaryforce to actuate the hook member 612 and further provides a mechanicaladvantage to draw the hook member 612 into the elongated slot 606 andcompress a header seal (not shown) located on the top of the windshieldframe 32. The header seal and the fabric of the soft top 12 provide aresistance force for keeping the latching mechanism 602 in tension suchthat the undercenter orientation retains the latch mechanism 602 closedand secure.

Turning to FIG. 13, the latching mechanism 604 for the hard top 14 isillustrated in its latched position. The hook member 612 and handle 610of the hard top latching mechanism 604 are identical in construction andfunction to corresponding elements of the soft top latching mechanism602. The base plates 618 of the hard top latching mechanism 604similarly function to pivotally interconnect the handle with the topheader 100 and are the only components not identical between thelatching mechanisms 602 and 604.

VII. MOTOR VEHICLE TOP SYSTEM IN WHICH THE HARD TOP MAY BE OPERATIVELYINSTALLED OVER THE FOLDED SOFT TOP

As noted above, the top system of the present invention allows the hardtop 14 to be operatively installed over the folded soft top 12. Onepurpose of this feature is to allow delivery of both tops 12 and 14 tothe customer. Another purpose is to allow for an expanded range of usesof the vehicle 10. The owner/user can have the hard top 14 on forgreater comfort and less noise on long trips and on arrival, take thehard top 14 off and have the soft top 12 for local use with the benefitof open air driving. The soft top 12 is ready to be moved to itsoperative position or retained in the stored position for availableprotection from the element from adverse weather conditions.

The ability of the top system to allow the hard top 14 to be operativelyinstalled over the folded soft top 12 is made possible largely in partdue to the several unique aspects of the present invention describedabove. For example, the soft top 12 folds back and is contained withinthe boundaries of the body side 18 and the tailgate area while having alow stack height. Additionally, the retainer members 500 welded onto thebody side section 58 allow the tops 12 and 14 to functioninterchangeably. As noted above, the captured nuts 509 carried in theretainer members 500 allow the hard top fasteners 78 to be easilyaccessible and installed even with the support bows 102-106 of the softtop 12 down in that area (as shown in FIG. 6). These features discussedabove combine to allow the soft top 12 to fit under the hard top 14. Inaddition, a lower rear portion (not specifically shown) of the hard topside section is configured with a clearance on each side to allow thesoft top 12 to fit under the hard top 14.

VIII. METHOD OF INSTALLING THE SOFT TOP

Installation of the soft top 12 utilizing the features of the presentinvention provides an improved method of tensioning the fabric of thesoft top 12. The preferred method, which is illustrated throughout thedrawings, includes the following general steps:

1. Articulating the soft top 12 from its stored position to itsoperative position (as shown in FIG. 8).

2. Engaging the latching mechanism 602 carried by the forward edge 50 ofthe soft top 12 with the windshield slot 606 by moving the handle 610from the upper (unlatched) position to the lower (latched) position (asshown in FIG. 12A).

3. Zipping the rear window 48 in the rear panel 40 and the quarterwindows 42 in the side sections 38 (as shown in FIG. 18).

4. Tucking in the retainers 400 into the horizontally oriented molded-inchannels 244 of the removable door frame assembly 200 (as shown in FIG.14).

5. Tucking the forward retainer 62 attached to the side section 38 ofthe soft top 12 into the vertically oriented molded-in channels 246 ofthe removable door frame assembly 200 (as shown in FIG. 15).

6. Tucking the retainer 80 of the side section 38 of the soft top 12into the slot 512 defined by the welded-on retainer 500 on top of thebody side panel 58, working from the front to the rear. As theseretainers 80 are tucked in, the soft top 12 is gradually tensionedagainst the flexing of the L-shaped members 116.

7. Finally, rear corner retainers 84 in the soft top cover 12 are tuckedin, effectively completing the securement and tensioning of the soft top12. The fabric stretched over the bows provides the soft top's totaltension (as shown in FIG. 19).

As noted above, the arrangement for articulating the soft top 12,especially the L-shaped members 116 connected to the #3 bow 104,provides a spring load which serves as a counter-force to the fabric.Thus, the method of attaching the soft top 12 effectively employs aspring load in the bow assembly structure and the fabric of the soft top12 without separate tensioning devices.

While the above description constitutes the preferred embodiment of thepresent invention, it will be appreciated that the invention issusceptible to modification, variation, and change without departingfrom the proper scope or fair meaning of the present invention. In thisregard, while the various features of the present invention have beenshown and described in connection with a specific motor vehicle, it willbe appreciated by those skilled in that art that many of these featuresare suitable in connection with motor vehicles.
